Definitions

  • the invention relates to a usable structural element in particular, but not limited to, as a support for front panel for motor vehicle.
  • EP 0 658 470 A describes such a front panel support comprising a plastic body molded onto a reinforcement metal in pressed sheet metal.
  • EP 0 370 342 A describes a structural element comprising a first component having the general shape of a channel having opposite free edges, and a second component in plastic material overmolded on the first component, defining at least one veil which extends transversely inside of the canal, and extending outside the canal in the region of said free edges.
  • the second component is not linked with the free edges of the first component only in areas discrete along these through openings there are spared.
  • the object of the invention is to obtain a more rigid connection between the second component and the free edges of the first component.
  • the invention relates in particular to a structural element of the kind defined above, and provides that each free edge is divided in its longitudinal direction in staggered sections relative to the others alternately inward and outward in the lateral direction of the channel, and that the second component forms a bead on each free edge longitudinal which covers the external face of the sections offset towards the inside and the internal face of the sections shifted outward.
  • the cord can thus be in connection with the free edge on the entire length of it, also serving as a support both inward and outward.
  • Figure 1 is a cross-sectional view of an element of composite structure according to the invention.
  • Figures 2 and 3 are perspective views, partially torn from two structural elements according to the invention.
  • Figures 2a and 3a are enlarged details of Figures 2 and 3 respectively, partially showing a free edge of the first component.
  • first component 1 in the form of a channel obtained for example by stamping a sheet of steel, and a second component 2 of overmolded plastic, for example by injection, on component 1.
  • Channel 1 is a part U-shaped profile comprising a bottom 3 and two side walls 4, 5, having, opposite the bottom 3, free edges respective 6, 7.
  • each free edge is divided into its longitudinal direction in sections offset by one relation to others alternately inward and toward outside in the lateral direction of the canal.
  • the free edge 6 includes interior sections 6a and outer sections 6b, and the edge 7 comprises sections interior 7a and exterior sections 7b.
  • Sections 6a and 6b (and of course also sections 7a and 7b) can be interconnected by inclined portions 6c relative to the longitudinal direction of edge 6, as shown in Figures 2 and 2a.
  • the sections 6a, 6b can end by free slices 6d, 6th resulting from cuts made in the sheet without removing material.
  • the second overmolded component comprises two cords 8, 9 extending respectively along the edges 6 and 7 of the channel, linked together by sails 10.
  • FIG. 1 illustrates, in its left half and in its right half, two provisions possible of the cord 8, 9 relative to the edges 6, 7.
  • this arrangement can be either the one on the left side or the one on the right side of figure 1.
  • the cord 9 on the right side covers only the external face of the interior sections 7a and the internal face outer sections 7b, and outcrop in height at longitudinal sections 7f of sections 7a.
  • the cords 8, 9 may have a cross section constant over their entire length.
  • the sections of the free edges 6, 7 shown on the Figures 1 and 3a are curved outwards, with a radius smaller curvature for the outer sections 6b, 7b as for the interior sections 6a, 7a.
  • the interior sections 6a can be planed as shown on the Figure 2a, and the interior and / or exterior sections can have a more complex profile like the sections exteriors 6b shown in Figure 2a.
  • Cords 8 and 9 are interconnected by a multiplicity sails 10 extending substantially in inclined planes relative to the longitudinal direction of the element and is crossing two by two halfway across it.
  • a multiplicity sails 10 extending substantially in inclined planes relative to the longitudinal direction of the element and is crossing two by two halfway across it.
  • a column 11 vertical, that is to say perpendicular to the bottom 3, of a diameter greater than the thickness of the sails, which is based on the bottom 3 by an enlarged base 12.
  • Each base 12 coats a projection 13 undercut produced by a deformation from the bottom 3 towards the inside of the canal, thus ensuring mechanical attachment of component 2 and bottom 3.
  • the second component is molded so as to present, as known per se, in particular outside of channel 1, parts suitable for fixing the devices on the support and for fixing this on the structure of the vehicle.
